Discovery of Potent Heterodimeric Antagonists of Inhibitor of Apoptosis Proteins (IAPs) with Sustained Antitumor Activity
The
prominent role of IAPs in controlling cell death and their
overexpression in a variety of cancers has prompted the development
of IAP antagonists as potential antitumor therapies. We describe the
identification of a series of heterodimeric antagonists with highly
potent antiproliferative activities in cIAP- and XIAP-dependent cell
lines. Compounds <b>15</b> and <b>17</b> further demonstrate
curative efficacy in human melanoma and lung cancer xenograft models
and are promising candidates for advanced studies

Dimeric Macrocyclic Antagonists of Inhibitor of Apoptosis Proteins for the Treatment of Cancer
A series of dimeric macrocyclic compounds
were prepared and evaluated
as antagonists for inhibitor of apoptosis proteins. The most potent
analogue <b>11</b>, which binds to XIAP and c-IAP proteins with
high affinity and induces caspase-3 activation and ultimately cell
apoptosis, inhibits growth of human melanoma and colorectal cell lines
at low nanomolar concentrations. Furthermore, compound <b>11</b> demonstrated significant antitumor activity in the A875 human melanoma
xenograft model at doses as low as 2 mg/kg on a q3d schedule
